……	……

The base station stores the corresponding relation between the value range of the load parameter and the load level and stores the corresponding relation between the QCI, the load level and the value of the wireless scheduling parameter. The load level is used for reflecting the load of the cell, the greater the load of the cell is, the higher the load level of the cell is, the smaller the load of the cell is, and the lower the load level of the cell is. For example, referring to the correspondence between the numerical ranges of the load parameters and the load levels shown in table 3 below, it is assumed that the base station divides the load levels of the cell into three levels, i.e., a light load level, a medium load level, and a heavy load level, and defines the numerical ranges of the load parameters corresponding to each load level.

The value of the wireless scheduling parameter may include at least one of a wireless scheduling weight and a minimum guaranteed rate, and so on, and the correspondence between the QCI, the load level and the value of the wireless scheduling parameter includes a correspondence between the QCI, the load level and the wireless scheduling weight and/or a correspondence between the QCI, the load level and the minimum guaranteed speed. For example, the base station may maintain the QCI, the correspondence of the load level and the wireless scheduling weight as shown in table 4 below, and may maintain the correspondence of the QCI, the load level and the minimum guaranteed speed as shown in table 5 below.

TABLE 4

QCI	Load class	Wireless scheduling weights
			1	Light load	100
1	Medium load	300
			1	Heavy load	600
2	Light load	100
			2	Medium load	400

			2	Medium load	330kb/s
2	Heavy load	600kb/s
			……	……	……

Referring to table 4 and table 5 above, the lower the load level of the cell, the smaller the difference between the values of the radio scheduling parameters corresponding to different QCIs. The higher the load level of the cell is, the larger the difference between the values of the radio scheduling parameters corresponding to different QCIs is.

Referring to fig. 2, a management end may be further included, and the management end may send, to the base station, a correspondence between the value range of the load parameter and the load level, and send a correspondence between the QCI, the load level, and the value of the wireless scheduling parameter. And the base station receives and stores the corresponding relation between the numerical range of the load parameter and the load level, and receives and stores the corresponding relation between the QCI, the load level and the numerical value of the wireless scheduling parameter.

The technical staff can set the corresponding relation between the value range of the load parameter and the load level and the corresponding relation between the QCI, the load level and the value of the wireless scheduling parameter at the management end. Then, the management terminal sends the corresponding relation between the value range of the load parameter and the load level and sends the corresponding relation between the QCI, the load level and the value of the wireless scheduling parameter to the base station.

Optionally, a technician may set a configuration file on the management terminal, where the configuration file stores a corresponding relationship between the value range of the load parameter and the load level, and a corresponding relationship between the QCI, the load level, and the value of the wireless scheduling parameter. The management terminal sends the configuration file to the base station, and correspondingly, the base station receives and stores the configuration file.

The connection between the UE and the core network comprises the connection between the UE and the base station and the connection between the base station and the core network, and when the connection between the UE and the core network is established, interactive messages between the UE and the core network are forwarded through the base station. In the process of establishing connection between the UE and the core network, the UE sends an establishment request message carrying the identity of the UE to the core network, the core network receives the establishment request message, acquires the identity type of the UE according to the identity of the UE carried by the establishment request message, acquires a QCI corresponding to the identity type of the UE from the corresponding relation between the identity type and the QCI according to the identity type of the UE, sends the QCI corresponding to the identity type of the UE to the base station, and the base station receives the QCI corresponding to the identity type of the UE. Alternatively, the first and second electrodes may be,

before the UE performs service transmission with a core network, the UE sends a request message carrying the service type of the service to the core network, the core network receives the request message, acquires QCI corresponding to the service transmitted by the UE from the corresponding relation between the service type and the QCI according to the service type carried by the request message, and sends the QCI corresponding to the service transmitted by the UE to a base station, and the base station receives the QCI corresponding to the service transmitted by the UE.

After receiving the QCI corresponding to the identity type of the UE or receiving the QCI corresponding to the service currently transmitted by the UE, the base station may obtain the value of the load parameter of the cell in which the UE is located, and determine the load level of the cell in which the UE is located according to the value of the load parameter and the corresponding relationship between the value range of the load parameter and the load level. And acquiring the numerical value of the wireless scheduling parameter from the corresponding relation among the QCI, the load grade and the numerical value of the wireless scheduling parameter according to the received QCI and the load grade, and acquiring the scheduling priority of the UE according to the numerical value of the wireless scheduling parameter. And scheduling the UE according to the scheduling priority.

After receiving the QCI, the base station may first obtain a scheduling priority of the UE, and when the UE needs to be scheduled, the base station schedules the UE according to the scheduling priority. Or, the base station acquires the scheduling priority according to the above mode when needing to schedule the UE, and schedules the UE according to the scheduling priority.

Optionally, when the base station sends data to the UE, the base station needs to schedule the UE, and after the UE is scheduled, the base station starts sending data to the UE. Or when the UE sends data to the base station, the UE sends a scheduling request to the base station, the base station receives the scheduling request and determines that the UE needs to be scheduled, and after the UE is scheduled, the UE sends data to the base station.

Optionally, the load parameter is used to describe a load size of the cell. The value of the load parameter may be the load size of the cell.

Referring to fig. 3, an embodiment of the present application provides a method for scheduling a device, where the method may be applied to a network architecture as shown in fig. 1 or 2, and the method flow includes:

step 201: the base station acquires a QCI, which corresponds to the identity type of the UE, or corresponds to a service currently transmitted by the UE.

In this step, the base station receives a QCI corresponding to the identity type of the UE sent by the core network, or receives a QCI corresponding to a service currently transmitted by the UE sent by the core network.

Before the UE sends data to the core network or receives data sent by the core network, the UE establishes a connection between the UE and the core network, where the connection between the UE and the core network includes a connection between the UE and a base station and a connection between the base station and the core network. When the UE establishes the connection with the core network, the UE sends an establishment request message carrying the identity of the UE to the core network, the core network receives the establishment request message, the identity type of the UE is obtained according to the identity of the UE carried by the establishment request message, a corresponding QCI is obtained from the corresponding relation between the identity type and the QCI according to the identity type of the UE, the obtained QCI is used as the QCI corresponding to the identity type of the UE, the QCI corresponding to the identity type of the UE is sent to the base station, and the base station receives the QCI corresponding to the identity type of the UE. Alternatively, the first and second electrodes may be,

Before the UE performs service transmission with a core network, the UE sends a request message carrying a service type of the service to the core network, the core network receives the request message, acquires a corresponding QCI from a corresponding relation between the service type and the QCI according to the service type carried by the request message, takes the acquired QCI as the QCI corresponding to the service transmitted by the UE, and sends the QCI corresponding to the service transmitted by the UE to a base station, and the base station receives the QCI corresponding to the service transmitted by the UE.

Before executing the step, when the UE registers in the core network, the UE sends the UE identity and the UE identity type to the core network. The core network receives the identity of the UE and the identity type of the UE, and stores the corresponding relation between the identity of the UE and the identity type of the UE in the corresponding relation between the identity of the UE and the identity type of the UE. Thus, when the core network acquires the identity type of the UE, the identity type of the UE is acquired from the corresponding relation between the identity of the UE and the identity type of the UE according to the identity of the UE.

Step 202: the base station acquires the value of the load parameter of the cell where the UE is located.

The load parameter includes at least one of the number of users accessing the cell and the utilization of Physical Resource Blocks (PRBs) of the cell.

The PRB corresponds to 12 consecutive carriers in the frequency domain (180K in the case of 15K carrier spacing) and resources in the time domain for one slot (half a subframe, 0.5 ms).

The base station may periodically obtain a value of a load parameter for the cell.

For example, the value of the load parameter of the cell where the base station acquires the UE is S, and it is assumed that S is greater than the first threshold and smaller than the second threshold.

Step 203: and the base station determines the load level of the cell according to the value of the load parameter and the corresponding relation between the value range of the load parameter and the load level.

The base station stores the corresponding relation between the numerical range of the load parameter and the load level. The base station acquires the corresponding relation between the stored numerical range of the load parameter and the load level, determines the numerical range of the load parameter where the numerical value of the load parameter is located from the numerical range of each load parameter stored in the corresponding relation between the numerical range of the load parameter and the load level, acquires the corresponding load level from the corresponding relation between the numerical range of the load parameter and the load level according to the numerical range of the load parameter where the numerical value of the load parameter is located, and takes the acquired load level as the load level of the cell.

For example, the correspondence relationship between the load range and the load level of the load parameter shown in table 3 includes three numerical ranges of the load parameter, which are respectively a first numerical range smaller than or equal to the first threshold, a second numerical range larger than the first threshold and smaller than the second threshold, and a third numerical range larger than or equal to the second threshold. The base station determines a second numerical range in which the numerical value S of the load parameter is located from the first numerical range, the second numerical range and the third numerical range, acquires a corresponding load level as "medium load" from the correspondence between the numerical range of the load parameter and the load level as shown in table 3 according to the second numerical range, and takes the acquired load level "medium load" as the load level of the cell.

When the load parameters include the number of users accessing the cell and the PRB utilization rate, the number of users and the PRB utilization rate may be weighted to obtain a composite parameter value. And taking the comprehensive parameter value as the numerical value of the load parameter, determining the numerical range of the load parameter where the comprehensive parameter value is located from the numerical range of each load parameter stored in the corresponding relation between the load parameter range and the load level, and acquiring the corresponding load level from the corresponding relation between the numerical range of the load parameter and the load level as the load level of the cell according to the determined numerical range of the load parameter.

Since the base station may periodically obtain the value of the load parameter of the cell, the base station obtains the load level of the cell through this step whenever obtaining the value of the load parameter of the cell, that is, the base station also periodically obtains the load level of the cell.

The load level of the cell may be constantly changing. In order to avoid reacquiring the scheduling priority for scheduling the UE as soon as the load level of the cell changes, m first load levels may be continuously acquired, where the m first load levels are load levels periodically acquired by the base station within a time period whose duration is a preset duration, and m is an integer greater than 1. If the m acquired first load levels are all the same and the first load level is different from a second load level, the step 204 may be performed, where the second load level is the load level acquired before the m first load levels are acquired, i.e. the second load level is the load level acquired last time between the time periods.

Referring to fig. 4, the base station periodically obtains the value of the load parameter of the cell from the first time t1 to the second time t2, the first time t1 is before the second time t2, the time duration between the first time t1 and the second time t2 is a preset time duration, and the load level of the cell is determined according to the value of the load parameter obtained each time and the corresponding relationship between the value range of the load parameter and the load level. For convenience of explanation, the m load levels obtained from the first time t1 to the second time t2 are referred to as a first load level, and m is an integer greater than 1. Referring to fig. 4, the m first load levels obtained from the first time t1 to the second time t2 are all "medium load", the first load level "medium load" is higher than the second load level "light load", and the second load level "light load" is the load level determined last before the first time t1, and the following operation of step 204 is started.

Step 204: and the base station acquires the numerical value of the wireless scheduling parameter from the corresponding relation among the load grade, the QCI and the numerical value of the wireless scheduling parameter according to the first load grade and the QCI.

The base station stores the corresponding relation between the load level, the QCI and the value of the wireless scheduling parameter, in the step, the base station obtains the corresponding relation between the stored load level, the QCI and the value of the wireless scheduling parameter, m first load levels determined from a first time t1 to a second time t2 are all equal and the first load levels are different from the second load levels, and the value of the wireless scheduling parameter is obtained from the corresponding relation between the load level, the QCI and the value of the wireless scheduling parameter according to the first load levels and the QCI at the second time t 2.

The wireless scheduling parameter may include at least one of a wireless scheduling weight and a minimum guaranteed rate, etc. In this step, the wireless scheduling weight may be obtained from a corresponding relationship between the load level, the QCI, and the wireless scheduling weight according to the first load level and the QCI, and/or the minimum guaranteed rate may be obtained from a corresponding relationship between the load level, the QCI, and the minimum guaranteed rate according to the first load level and the QCI.

For example, assuming that the obtained QCI is 1, referring to fig. 4, the first load levels obtained by the base station from the first time t1 to the second time t2 are both "medium load" and are different from the second load level "light load" obtained before the first time t1, so in this step, according to the first load level "medium load" and the QCI "1", the wireless scheduling weight is 300 from the corresponding relationship of the load level, the QCI, and the wireless scheduling weight shown in table 4, and according to the first load level "medium load" and the QCI "1", the minimum guaranteed rate is 100kb/s from the corresponding relationship of the load level, the QCI, and the minimum guaranteed rate shown in table 5.

Step 205: and the base station acquires the scheduling priority of the UE according to the numerical value of the wireless scheduling parameter, wherein the scheduling priority is used for describing the scheduling sequence of the UE by the base station.

In this step, the base station may obtain the scheduling priority of the UE through the following first formula.

The first formula is:

in the first formula, Priority is a scheduling Priority of the UE, and eff is a channel quality of the UE.

Alpha is a capacity factor initially configured by the base station.

When the capacity factor is equal to 1, the selection of Non-guaranteed bit rate (Non-GBR) service priority follows the scheduling resource fairness principle.

When the capacity factor is less than 1, the selection of priority for Non-GBR service is inclined to the rate fairness principle.

When the capacity factor is larger than 1, the selection of Non-GBR service priority is shown to be inclined to the principle of capacity priority.

r is the rate of the UE historical transmission.

Y_QCIThe value of the wireless scheduling parameter may be a wireless scheduling weight, or may be a minimum guaranteed rate, or may be a result of performing weighted calculation on the wireless scheduling weight and the minimum guaranteed rate.

Coeff_SPIDThe downlink scheduling priority weighting coefficient of a Service Profile Identifier (SPID) user, which is pre-configured for the base station, is valid only when the base station normally identifies that the UE is a SPID user.

f (delay) is the time delay of waiting scheduling of the UE at the base station side, which can be obtained by timing by the base station.

After obtaining the scheduling priority of the UE, the base station may store the scheduling priority of the UE.

After the step is executed, that is, after the second time, the load level of the cell is still periodically acquired, and assuming that the load level of the cell acquired at the third time is changed, the third time is after the second time, for convenience of description, the load level of the cell periodically acquired within the third time to the fourth time is called as a third load level, the third time is before the fourth time, and the duration of the third time to the fourth time is a preset duration. And if the third load levels periodically acquired from the third time to the fourth time are equal and the third load levels are different from the first load levels, acquiring the scheduling priority of the UE at the fourth time according to the QCI and the third load levels, and replacing the stored scheduling priority of the UE with the acquired scheduling priority.

The detailed procedure of the base station acquiring the scheduling priority of the UE according to the QCI and the third load level can be referred to the content of the above steps 204 to 205, and is not described in detail herein.

For example, referring to fig. 4, after the second time t2 to the third time t3, the base station periodically obtains that the load level of the cell is the first load level, the first load level is "medium load", and in the third time t3 to the fourth time t4, the base station periodically obtains that the third load level of the cell is equal, the third load level is "heavy load" and is higher than the first load level "medium load", so that at the fourth time t4, the scheduling priority of the UE is obtained according to the QCI and the third load level, and the duration between the third time t3 and the fourth time t4 is a preset duration.

Step 206: and when the base station schedules the UE, the UE is scheduled according to the scheduling priority of the UE.

The base station may need to transmit data to the UE, or the UE may need to transmit data to the base station. Before the base station sends data to the UE, the base station schedules the UE according to the stored scheduling priority of the UE, and the base station sends the data to the UE after the UE is scheduled. Before the UE sends data to the base station, the UE sends a scheduling request to the base station, after the base station receives the scheduling request, the UE is scheduled according to the stored scheduling priority of the UE, and the UE is scheduled to send data to the base station. Or, when the base station needs to schedule the UE, the base station executes the above steps 202 to 206 to obtain the scheduling priority, and schedules the UE according to the scheduling priority.

And the base station sorts according to the scheduling priority of the UE and schedules the UE according to the sorted sequence.

In the correspondence relationship between the QCI, the load level, and the values of the wireless scheduling parameters, the lower the load level of the network is, the smaller the difference between the values of the wireless scheduling parameters corresponding to different QCIs. Under the condition that the load level of a cell is lower, the load of a network is lower, and at the moment, idle resources of a base station are more, so that the difference value between the numerical values of the wireless scheduling parameters corresponding to different QCIs is smaller, the difference between the numerical values of the wireless scheduling parameters of different UEs obtained in the way is smaller, the difference between the scheduling priorities of the UEs obtained based on the numerical values of the wireless scheduling parameters of the UEs is smaller, and therefore when each UE is scheduled according to the scheduling priority of the UE, each UE obtains relatively uniform scheduling opportunities, and the QoS of the UE is improved.

In the correspondence relationship among the QCI, the load level, and the value of the wireless scheduling parameter, the greater the difference between the values of the wireless scheduling parameters corresponding to different QCIs, the greater the value of the wireless scheduling parameter corresponding to a larger QCI is than the value of the wireless scheduling parameter corresponding to a smaller QCI. When the load level of the network is higher, the load of the network is higher, and at this time, the idle resources of the base station are less, so that the difference between the value of the radio scheduling parameter corresponding to the larger QCI and the value of the radio scheduling parameter corresponding to the smaller QCI is larger. The larger QCI is usually a QCI corresponding to a VIP user or a VVIP user UE, or is usually a QCI corresponding to a high-priority service, so that the value of the wireless scheduling parameter obtained for the VIP user or the VVIP user UE or the UE transmitting the high-priority service is larger, and the scheduling priority of the UE obtained based on the value of the wireless scheduling parameter of the UE is also larger, so that when the UE is scheduled according to the scheduling priority of the UE, the scheduling opportunity obtained by the UE is higher, thereby improving the QoS of the VIP user or the VVIP user UE or the UE transmitting the high-priority service.

In the embodiment of the application, the value of the load parameter of the cell where the UE is located is obtained, the load level of the cell is obtained according to the value of the load parameter, and the value of the wireless scheduling parameter is obtained according to the QCI corresponding to the identity type of the UE or the service transmitted by the UE and the load level, so that the value of the wireless scheduling parameter under the appropriate condition is obtained under different conditions for the load of the cell, thereby obtaining the scheduling priority based on the value of the wireless scheduling parameter, and improving the QoS of the UE when the UE is scheduled according to the scheduling priority. In addition, when the numerical value of the wireless scheduling parameter is acquired, the load level of the cell is acquired periodically, and when the load level acquired for a period of time is the same and is different from the load level acquired before the period of time, the scheduling priority is calculated according to the load level acquired within the period of time and the QCI, so that frequent calculation of the scheduling priority can be avoided, and occupation of base station computing resources is reduced.
